The present invention relatesto filing apparatus of the type wherein aplurality'of cards are secured upon the periphery of a rotatablefilingdrum, to facilitate access to a' greatplu'ralityof cards by anoperatrirJjTheinvention includes modification of, improvements upon, andadditions to filing apparatus of the type shown in the prior patent to"Scholfieldet al.

An object of the present invention is t provide improved card retaining"rail-structures,

adapted to perform certain new" and improv d functions, a i

' A further object of the invention isto provide improved card retainingmeans whereby a plurality of cards may be removed simultaneously or enbloc from the-periphery of the "drum.

'A further object of the invention is ,to provide improved card'railshapes and cards having novel slots therein adapted to cooperate withthe rails,

to secure the cards thereon in an improved manner. v

With filing drums of the type shown in the aforementioned patents,-the-- cards are placed upon the card retaining rails by fiexingthematerial of the card adjacentf'the-keyhole-shaped slots therein, therebyeffectively but temporarily widening the opening at the narrowv throatsof the slots and permitting themto-move'bver the rail heads-For a greatmanyuses', drum -and cards of that type are entirely satisfactory,- butin some cases, it is desirable toremove, from a drum, ajrelatively greatplurality of cards simultaneously; as a group. *The presentinventionprovides a construction wherein the cards may 'be readily removed fromthe drum periphery by radial movement. 1 '1 I A-preferred-einbodiment ofthe invention is shown in the accompanyingdrawings, but it must beunderstood that the invention isnot limited to' the specific details orconstruction shown therein and described below, as many modificationswill readily occur to one skilled in the-art, from a consideration ofthe disclosure of this specification.

In thatpatent, a continuousrail is disclosed, but, in accordancewith thepresent invention, the'rail is'interrupted,

for instance, atfour'spaced points around the circumference of the drum,where the rim is apertured as at 21. rim adjacentthe ends of theopenings, is provided with downwardly projecting lugs 22 whichareisocketed to receive pintles 23, 24 of a pivoted member 25" havingtwo 'webs projecting radially in right pintles. One web 26 has the samecross sectional the outer edge'of the web. The other web 28is-plane-sided and terminates at its outer edge in 'a free, non-headedend Appropriate means, su'chas a spring pressed latch 30 (Fig; 2) ispr0Vid'ed,'-to hold the member '25 in either ofits two positions, asshown in Figures 3 and 4,- respectively. i

" When the pivoted member 25 is in the posi 'ti'on shown in Figures 1, 2and i, thefihead-Zl "constitutes a continuation of the'fixed rail 20and; therefore, the card retaining railis con- 1 tinuous around theentire circumference of the drum. Ifthe'member 231's swung to the otherposition assshown in FigureB, however, the'non- 2,205,932, June 25,1940..

The inner surface of the angular relation from the axis of the headedweb 28 is aligned with the fixed card taining rail. When cards are movedonto this rail section, they may be removed therefrom by radialmovement, en bloc, since no head 21 is disposed within thekeyhole-shaped openings 3| of the cards.

If desired, the outer edge 29 of the web may be of increasingheightflrom end to end, so that, as the cards are movedcircumferentially onto that web, the edge 29 will engage the inner edgesof the keyhole slots '3! and project the cards outwardly beyond theadjacent cards on the fixed re- I rail section, thereby facilitatingremoval of the cards from the drum.

In this form of the invention, both the fixed card retaining railsection and the movable card retaining rail section have their heads 21constructed in accordance with the disclosure'of my prior Patent2,231,029, whereby the circular apertures in the cards make a linecontact with the railhead, as shown in'Figures 4 and-5 and as describedin the aforesaid patent.

Itwill thus be seen that, in accordance with the present invention, aplane-sided, non-headed rail section may be aligned with a fixed railsection, so that cards moved from the latter onto the former, may beremoved'th'erefrom en bloc by radial movement relative to the non-headedsection.

The filing drum of the present invention may be used in conventionalmanner, in accordance with the disclosures ofthe patents mentionedabove. However, if it is desired to remove a plurality of cardssimultaneously from the drum, or i to place a relatively large group ofcards thereon at the same time, it is simply necessary to swing theheaded rail section laterally to a position below the drum peripherythereby bringing the nonheaded section 28 into alignment with the fixedheaded section; Cards may then be placed upon or removed from thenon-headed sectionby radial movement.
